Patented July 3, 1934 VEHICLE-BRAKE SHIELD George R. Cunnington, Akron, Ohio, assignor to The Paine-Cunnington Company, Cleveland, Ohio, a corporation of Ohio Application March 13,

16 Claims.

This invention relates to shields for vehicle brakes, and more particularly brakes of the type in which the brake housing is mounted in connection with the wheel, such housing having a rotary portion moving with the wheel and a stationary closure member supported on the axle structure. It is among the objects of the invention to provide a shield construction which is not only simply and easily applied, but which affords ample breathing for air circulation. Other objects and advantages will appear as the description proceeds.

To the accomplishment of the foregoing and related ends, the invention, then, consists of the features hereinafter fully described, and particularly pointed out in the claims, the following description and the annexed drawing setting forth in detail certain structures embodying the invention, such being illustrative however of but a few of the various ways in which the principle of the invention may be employed.

In said annexed drawing:

Fig. 1 is a face View in elevation showing an embodiment of the invention; Fig. 2 is a fragmentary part-sectional detail on an enlarged scale showing the assembly relationship; Fig. 3 is a face view in elevation showing another form; Fig. 4 is a detail analogous to that of Fig. 2, likewise on enlarged scale; Fig. 5 is an enlarged fragmentary detail in elevation showing the connecting means; and Fig. 6 is a view analogous to Fig. 2 and showing another modification.

Referring more particularly to the drawing,

there is shown a shield in the form of a transversely split annular member 2 having a portion or zone 3 engageable on the stationary plate 4 closing a brake housing, and a portion or zone 5 lapping over the margin of the rotary portion 6 of a vehicle brake drum housing, the latter being secured in any usual or preferred way to the wheel whose spokes 7 are in adjacent relationship with the housing in general. By pro- Viding the shield in the'form of a split ring, the ends 8, 9 thereof may space apart slightly when in position on the brake drum housing, such spacing being slight, but sufficient however to permit free breathing or air interchange within, and facilitate cooling of the brake elements in use. At the same time, the closure elsewhere is complete, and by positioning the opening or interruption of the ring at a favorable point, preferably in a lower segment, all of the utilities of complete closure may be had without interference with air circulation in desirable volume and without detrimental entrance of water- 1930, Serial No. 435,439

or dirt at the breathing point. Preferably, the ring 2 is held over the joint of the brake drum assembly by engagement not necessitating fastening means to pass through the ring into the adjacent brake drum element. That is, the 60. shield is desirably held in place by a frictional grip or clamping hold, and by incorporating in the ring, as a whole or as a part thereof, a quantum of resiliency, the shield may be adequately and simply held in its proper position. Such resiliency may in some instances be had by a metallic construction in whole or in part, and desirably the engaging zone of the ring will fit sufficiently closely in its overlap, or embody an elastic zone or lip of yieldable material, to whether for example fabric, rubber or reenforced rubber to adequately seal. If the ring be made completely of rubber, it may be cured or vulcanized to provide a material degree of resiliency. With all such split ring forms, it is important Z5 that the ends of the ring be urged toward each other such as to hold the assemblage in proper engagement. With a rubber construction, it is advantageous generally to incorporate also a metal reenforce. This may take the form of a 8i split metal ring 10 carried in the rubber in one zone or flange, and such metal ring may afford further an amount of resiliency such as to allow the ring to be spread for convenient placement over the flange edges of the brake drum housing assembly and then hold snugly in position thereon. The other portion or zone of the ring 5 may curve over into lapping relation with the portion 6 of the brake housing, thereby guarding the joint and with firm and readily changeable po- 9(1) sitioning, without necessity of recourse to screws or bolts taken into any brake housing element.

In the form shown in Figs. 3-5, the metal reenforce 10' in the rubber ring 2 is arranged for a connector, the ends of the split metal ring 10 being projected out laterally as lugs 11, and through apertures in these a takeup bolt 12 may be arranged, the tightening of this serving to hold the ring in position securely against any possible stress from misalignment in the brake roe housing parts.

In Fig. 6 is shown another prevalent type of brake housing assembly with my shield in position, the assembly comprising brake drum housing 6' and co-operating member 4', and upon the member 4' the shield with its zone or flange portion 3 seating closely and the zone or flange portion 5' lapping over the adjacent member 6. As in the foregoing forms, the shield as a split ring is desirably held in place by a frictional llO grip or clamping hold, by resiliency of its own or an accompanying reenforce. A metal reenforce 10 for instance is desirable, and if further preferred its ends may be held by a takeup bolt. The flange portion 5 at least is yieldable (whether of rubber, fabric or other material) to adequately seal over the joint. In the figures of the drawing clearances are shown considerably exaggerated, for clarity. I

Other modes of applying the principle of the invention may be employed, change being made as regards the details disclosed, provided the means stated in any of the following claims, or the equivalent of such, be employed.

I therefore particularly point out and distinctly claim as my invention:-

1. A shield for vehicle brakes, comprising a transversely split annular member providing a guard across stationary and rotary portions of brake-housing, the ends of the annular member being unconnected and being urged toward each other.

2. A shield for vehicle brakes, comprising a transversely split annular member providing a guard across stationary and rotary portions of brake-housing, and means tending to urge the ends of the annular member toward each other unconnectedly.

3. A shield for vehicle brakes, comprising a channeled transversely split annular member providing a guard across stationary and rotary portions of brake housing, and having a soft protecting edge lip.

4. A shield for vehicle brakes, comprising a channeled transversely split annular member providing a guard across stationary and rotary portions of brake housing, and having a soft protecting edge lip, the ends of the annular member being urged toward each other.

5. A shield for vehicle brakes, comprising a channeled transversely split annular rubber member providing a guard across stationary and rotary portions of brake housing, the ends of the annular member being urged toward each other.

6. A shield for vehicle brakes, comprising a channeled transversely split annular member providing a guard across stationary and rotary portions of brake housing, said member having a soft protecting edge-lip, and means tending to urge the ends of the annular member toward each other.

7. A shield for vehicle brakes, comprising a channeled transversely split annular rubber member providing a guard across stationary and rotary portions of brake housing, said member having a soft protecting edge-lip, and means tending to urge the ends of the annular member toward each other.
